CMAS C. CUNNINGHAM,

BARE-WlRE MACHINE.

SPECIFICATION forming part of Letters Patent No. 323,490, dated .August4, 1885.

Application filed May 13, 1864.

To all whom, t may concern:

Be it known that I, CHARLES H. BAKER, a citizen of the United States ofAmerica. rcsiding at Knoxville, in the county of Marion and State ofIowa, have invented certain new and useful Improvements in Ba1b\Vi1'eMachines, of which the following is a specication, reference being hadtherein to the accompanying drawings.

My invention relates to an improved machine for attaching barbs tofence-wires, its object being to obtain a machine which will do its workwith celerity and certainty.

To the accomplishment of the above,the invention consists ofthe noveldevices and combinations of devices, as will be described and claimed.

Reference will be made to the accompanying drawings, in which Figure lis a plan view Figs. 2, 3, and 4, details, and Figs. 5, 6, 7, S, 9, andl0, views showing the different positions of the barb and fence wiresduring the operation.

Like letters refer to like partsin each view.

A. represents the bed-plate of the machine, and B the maindriving-shaft, which has suitable bearings in the framework thereof. Apulley, C, and cogwheehD are keyed to shaft T, the pulley for impartingmotion to said 3o shaft and the cog, and the cog for imparting motion toa shaft, E, through the medium of a cog, F, keyed thereto, said shaft Ebeing mounted in suitable bearings, G, and having keyed to its inner endabevel, H, which in its revolution meshes with a bevel, I, keyed to ashaft, K. This shaft K is suitably mounted in a support, L, formed uponbed-plate A, and protrudes a short distance beyond its support at itsfront end, and to the front end of said sha-ft there is secured anozzle, M, as shown in Fig, l. To the rear end of shaft K there is keyeda cog, N, which in its revolution meshes with a cog, O, keyed to a shortshaft, I), suitably mounted in bearing Q, and to the Vfront end of whichan eccentric wheel, R, is

keyed. The pin a of eccentric Renters and moves in acaxn-wheel, S, keyedto a shaft, T, which has bearings in a tube, T', mounted in support L,but which is so placed relatively 5o to shaft K that the front end ofthe nozzle U,

(No model.)

which is secured to it, willV occupy a position near to the nozzle ofshaft K,so as to bring the wires close together, as will be described.Keyed to tube T', at the point shown in Fig.

l, isa bevel, V, with which asegmental gear, W, meshes. Gear I is formedupon one end of an arm, K, upon the opposite end of which a toothedcam,Y,is formed. Cam Y is driven through the medium of arms Y and Z, andcam Z from the main shaft and at suitable 6o intervals partly revolvestube T', for the purpose hereinafter described. Upon the front end ofnozzles M and U, respectively, there are formed pins b c, and eachnozzle and t-he shaft to which it is secured is perforated its 6 5entire length for the passage therethrough of fence-wires A'B.

The operation is as follows: The fencewires are fed through shafts K andT, and the barb wire fed below said wires and above wrap- 7o pingpins bc, as shown in Fig. 5. Motion is then imparted to the maindriving-shaft, and through the connections described the shafts K and Tare revolved. The revolution and speed of the two shafts are equal untilthe barb-wire is bent to the position shown in Fig. 6, when, because ofthe arrangement of cani S with the other parts, the shaft T begins torevolve at a greater speed and carries one point of the barb-wirefarther around 8o wire A. than does the pin of shaft K, as shown in Fig.7. When this part of the barb-wire has been carried far enough to avoidall danger of the two ends contacting, the speed of shaftT is slackenedand the shaft K gradu- S5 ally gains on ituntil the two ends of thebarbwire are wrapped around their respective wires equally, these stopsbeing shown in Figs. 8 and 9. The revolution then continuing the barb iscompletely wrapped, as indi- 9o cated in Fig. 10, and through the mediumof segmental gear XV and its connections "with the main shaft and thetube T, in which shaft T in mounted, said tube is partly revolved andshaft T carried closer to shaftKtobring wires A B close together, asshown in Fig. 10.

Nhat I claim is I. The combination of two tubes perforatedlongitudinally for the passage of fencewires,

means for revolving said tubes, wrapping-pins 10o formed thereon forwrapping the barb-Wires, and mechanism constructed and arranged forvarying the speed ofA one of said tubes, substantially as described andshown.

5 2. The combination of two tubes perforated longitudinally for thepassage of fence-Wires, Wrapping-pins formed thereon for Wrapping thebarb-wires, mechanism for varying the speed of one of said tubes, andmechanism io'for changing the position of said tube with respect to theremaining tubes, substantially as described and shown.

3. The combination, with shafts TK,havng Wrapping-pins b and c, andmeans for revolv- I 5 ing them, shaft T being mounted eccentrically
